Application August 24,1942, Serial No. 455,876

3 Claims.

The invention described and claimed herein relates to improvements in fuel economizers for heating furnaces usually having a fire pot and a combustion chamber; and the objects of improvement are: first, to provide a fuel economizer for heating furnaces that can be freed of cinders without the necessity of entering the furnace; second, to provide a fuel economizer for heating furnaces that can be cleaned of carbon accumulation without entering the furnace; third, to provide a fuel economizer for heating furnaces that will be rugged and not liable to become cracked from repeated heating and cooling; fourth, to provide a fuel economizer for heating furnaces that can be readily removed from the furnace; fifth, to provide a fuel economizer for heating furnaces that can be mounted in the furnace without the necessity of entering the furnace; these named objects and such other objects as may appear from a perusal of the following description and the accompanying drawing are attained by the structure disclosed in the said accompanying drawing, in which Figure 1 is an elevation View of a heating furnace in part section and showing the fuel economizer mounted in front of the products of com bustion outlet flue and adjacent to said flue.

Figure 2 is an elevation view of the convex front of the fuel economizer.

Figure 3 is a side elevation view of the economizer mounted in front of the products of combustion outlet flue and against the wall of the combustion chamber of the furnace.

Throughout the views of the accompanying drawing similar numeral characters refer to similar parts or portions of my fuel economizer structure, and referring thereto.

Numeral I refers to a heating furnace as a whole having a fire pot 2 with the combustion chamber base ring 3 resting thereon and supporting the drum-like combustion chamber 4 having at one of its sides, opening 5 through which the fuel is fed to the fire pot of the furnace, the opening 5 is bounded by frame 6 extending from the opening through the wall of the combustion chamber through the outer casing 1 where the frame is closed by door 8 having an outwardly extending frame closed by draft break upwardly swingable door 9.- Numeral I0 refers to the fuel economizer element which is removably hung and slidable upward on brackets I I and in front of the products of combustion outlet flue I2. The fuel economizer consists of the metal body Ill having convex front I3 and concave back I4 with its lower end I5 of substan- 55 been found tially scoop shape and conforming to the curvature of the inner periphery of the combustion chamber casing. At the upper portion of the economizer element II] is recesses I6 each of which has an outwardly extending flange I'I having hole I8 of somewhat crescent shape and whereby the fuel economizer is hung on the brackets I I secured to the inner periphery of the combustion chamber wall in horizontally spaced apart relation to each other and above the axis of the products of combustion outlet flue I2. At the lower extremity of the economizer element is notch I9 in which a metal hook similar to that of a fire poker extended from outside the furnace through the opening 5 and frame 6 can be inserted to lift the economizer element from the brackets II or to swing the lower end of the fuel economizer away from the inner peripherial of the combustion chamber and thereby allow cinders that have accumulated at the concave back of the fuel economizer element to drop out, or to remove the fuel economizer element without the necessity of crawling into the furnace and removing retaining nuts or bolts. Numeral 2|] designates a flanged cover plate for closing the combustion chamber at its top.

Until the advent of my improved fuel econo-' mixer for furnaces, a bafile plate was bolted to lugs extending from the wall of the combustion chamber and in front of the products of combustion outlet flue. These plates served in a way but were not satisfactory, as cinders carried by the draft of the stack associated with the fur nace, accumulated between the p e and the wall of the combustion chamber and could not be removed without crawling into the furnace after it had been cooled sufficiently and unscrewing the retaining nuts from the bolts holding the plate in position and then removing the plate; while with my improved fuel economizer it is only necessary to extenda hook-formed poker bar through the opening 5 and frame 6, engage the lower end of the economizer element at the notch I9 and lift the economizer element from the brackets II for removal from the furnace or to raise or slide the fuel economizer on the brackets I I and force the economizer away from 'the wall of the combustion chamber and allow the cinder accumulation to drop out, or should the accumulation of cinder be caked and refuse to drop, the economizer can be pulled away from the combustion chamber wall and allowed to slam down on the brackets and against the wall of the combustion chamber which procedure has to not only jar the caked cinders 2. In an economizer for heating furnaces: a

concavoconvex metal body having a pocket adja-.

cent each of its Vertically extending sides near its top with a flange forming the bottom of each pocket and having an orifice extending therethrough by virtue of Which the economizer may be hung within the furnace.

3. An economizer for heating furnaces: a concavoconvex shovel-like metal body havin a pocket adjacent each of its vertically extending sides with an outwardly extending flange forming the bottom of each pocket and having an orifice extending through the flange by virtue of which the economizer can be hung within the furnace.
